You can add the Squadron Sinister, who are another Marvel take on the JLA; the Crusaders, Marvel's take on the Freedom Fighters (who appeared in Invaders the same month as DC's Crusaders appeared in Freedom Fighters); the Recombatants, DC's homage to the DNAgents who appeared in Teen Titans, and, if Comicvine had entries on them, Project Youngblood, which was the DNAgents' homage to the Teen Titans.

There's more analogues of British heroes by Alan Moore in his Captain Britain strips, Grant Morrison in his Zenith strip, Paul Grist in Jack Staff, Ian Edginton in The Establishment, and Warren Ellis in Stormwatch, but most don't have Comicvine entries.
